The error could be related to how the IDO variable is being deserialized or called via the SDK. Ensure that the object ID passed to the function is correctly formatted and recognized by the Sui Move environment .

The error might also stem from the Move function expecting different input types than what is being provided from the SDK call. Double-check that the Coin and other arguments match the expected types in the contract .

Ensure that any SDK methods used adhere to the correct structured data requirements, including expected object formats, particularly when dealing with cryptographic objects or transactions .

If you're using TypeScript's Sui SDK, verify the object ID is correct. Errors often arise from incorrect parameter or type handling in the SDK or the ID not being properly formatted .
